Washington (CNN) - Tea Party activists are becoming engaged in the nomination fight over who will replace retiring Justice John Paul Stevens on the Supreme Court. But differing tactics may end up putting different Tea Party groups at odds.

A Tea Party Express leader exclusively gave CNN a draft copy of a Tea Party Federation document that the organization is calling a "guideline" for picking a Supreme Court justice. This follows President Obama's nomination of Solicitor General Elena Kagan to the high court. Once the document is finalized it will be immediately distributed to Tea Party activists to use as a guide as they request meetings with key senators to discuss Kagan's nomination.

The plan that was revealed to CNN lays out, "Five Constitutional principles." Among those listed are: "Judges must interpret the Constitution of the United States as written," "Judges must not use their positions to replace the text of the law and Constitution of the United States with their own personal feelings or experiences," and "Judges must understand that the Federal government has no power if the Constitution does not explicitly provide it."

New York Rep. Dan Maffei’s office has been inundated with phone calls from people opposed to Democratic health care reform calling from outside of his congressional district.

Washington (CNN) - As a vote on health care reform nears, Republican and conservative groups are attempting to defeat the bill by pressuring undecided and vulnerable Democrats to vote against the legislation.

Bob Adams, the executive director of the League of American Voters, tells CNN that his organization will place a $547,000 television ad buy on Monday which will target 21 legislators. The group has spent $330,000 running ads since February 27.

The group has listed on their Web site the name and phone number of every Democrat who voted against the House's health care bill in November, as well as those of the 21 Democrats who voted "yea" in November but may change their vote.

As the phone lines jam, the offices of some of those Democrats are expressing frustration that their constituents may be unable to reach out.

New York Rep. Dan Maffei's press secretary Abby Gardner told CNN that her office was averaging about 500 phone calls per day last week, but that only 20 or so were from constituents in Maffei's district.

"The calls from the district are very mixed pro/for [and] against health care legislation," Gardner said. "The calls from outside of the district are exclusively against health care."

"Unfortunately the call volume makes it difficult for people to get through, and while I think the groups who really generate these calls consider jamming our phone lines a sign of strength and success, it really doesn't do anything to persuade the Rep.'s opinion on how to vote," Gardner said.
